I have an 08 6.0L suburban.

Until a few days ago my ac/heat controls worked fine, as well as the back lights on the temperature dials and on the rotary dials. I was able to turn on and off the rear defroster and AC with no problem .

All of a sudden 3 days ago, the backlight on the temperature dial and the backlight on the 2 rotary dials stopped working, (all the other backlights on the rest of that component are working), and the AC button, rear defroster button dont work and the fan speed selectors won't work on any speed setting. I checked the fuses and nothing seems to be blown


Any thought? Its getting cold and i need my climate controls

TIA

 

Coupled with your radio issues, I'd be inclined to say you've got grounding issues. Check your grounds and battery wires.
